FRED BROTHERHOOD, OF CHARLESTON, SOUTH CAROLINA.

APPARATUS FOR WASHHNGFPHOSPHATE ROCK, GRES', 8M).

SPECIFICATION forming part of Letters Patent No. 299,337, dated May 27, 1884.

Application filed January 23, 1884. (No model.)

To all whom it may conceive:

Charleston, South Carolina, have invented,

certain new and useful Improvements in Apparatus for Vashing Phosphate Rock, Orcs, &c., of which the followingis a specification.

My invention relates to improvements in apparatus, especially designed for washing phosphate rock, of the class in which the material to be washed is delivered into the lower end of an inclined rotating cylinder, upon the inner surface of which there is arranged a spiral or screw-like rib or series of ribs, by which the material being treated is gradually conducted from the lower to the upper end of the cylinder and discharged, while the refuse substances-such as sand, mud, Ste-are forced out at the lower end of the cylinder by means of a current of water passing through it. My object is to provide washing apparatus for most effectually cleansing the material, and which shall be strong and of economical construction.

My improvements, hereinafter particularly designated in the claims, as shown in the accompanying drawings, are adapted for use upon a vessel, so that the phosphate rock as dredged and crushed by suitable appliances may be delivered to the washing apparatus and discharged from it into other vessels or lighters.

In the drawings, Figure l is a view, partly in side elevation and partly in vertical section, with some of the parts broken away. Fig. 2 is a view, partly in end elevation and partly in section, on the line 2 2 of Fig. l. Fig. 3 is a view, partly in end elevation and partly in section, on the line 3 3 of Fig. l. Fig. 4 is a detailed view, partly in section, showing in part the forked conductor by which the material is directed to the washing-cylinders, and parts of the perforated pipes for supplying water to the cylinders. Fig. 5 is a transverse section on the line 5 5 of Fig, 7. Fig. 6 is a similar section on the line 6 6 of Fig. 7. Fig. 7 is a view in elevation, with parts broken away, representing the manner of securing a ring-gear about the cylinder. Figs. 8, 9, and

10 represent transverse sections on the lines 8 8, 9 9, and l0 l0, respectively, of Fig. Il. Fig. 1l is a View in elevation, with parts broken away, representing the manner of securing one of the supporting-ring wheels about the cylinder. Fig. l2 is a view, partly in elevation and partlyV in vertical section, with some parts broken away, representing the manner of arranging a pair of the cylinders upon the hull of a dredge-boat or other vessel.

Two cylinders, A A, of stout boiler-iron, and similar in construction, are each made as follows: The cylinders rotate about inclined axes (see Fig. l2, and dotted lines, Fig. 1,) indicatin g the angle of inclination. At the lower or inner ends of the cylinders they have short inwardly -flaring sections A A, perforated With numerous small openings 5 or, if preferred, a skeleton frame may be substituted for the perforated sheet-metal inwardly-flaring section, and the frame thus formed be covered with steelwire net-work. Each of these inwardly-iiaring sections is secured by ianges and rivets to the body of the cylinder in an obvious way. To give the required strength to the sections, they are preferably made of two thicknesses of metal riveted together. (See Fig. 1.) At the upper or outer ends of the cylinders they are provided with short out wardly-iiaring sections A2 A2, perforated and of double thickness, as are the just above described sections A. Arranged upon the inner surfaces of the cylinders in spiral or screwlike form are projections a, formed with perforated base-flanges a and lugs c2, by which to secure them in place by bolts or rivets.

These projections or rib-sections are arranged so that at their adjacent ends they approach very closely to each other, leaving only very narrow spaces between them, to admit of sand,

'mud, Sie., passing downward and out at the lower ends of the cylinders, as the material 9o to be washed is carried forward and upward, as hereinafter will be made apparent. These rib sections may either be slightly staggered or arranged in the same continuous spiral line. Each cylinder is provided with a ringgear, B, which is detachably secu-red to the cylinder in the following way: A band, C, is fitted tightly about the cylinder -and riveted or bolted thereto, so as to give increased strength, and

a strong cast-iron ring, C', is secured about Ioo this `band by the same bolts, b, and nuts which attach or assist in attaching the band to the a slightly-inclined or beveled surface and a continuous side rib or edge ange, c. Intermediate these inner and outer iianges, b c, the ring is formed with a slotted web, so as to reduce its weight to the prop er limit. rIhe ringgear, which is slightly beveled on its inner surface, is drawn in place about the cast-iron ring, and against the peripheral edge-flange c thereof, by means of a series of bolts, D, and their nuts d. These bolts are formed with square body portions, (those portions intermediateV the heads and threaded ends of the bolts,) lwhich pass through recesses formed partly in the flange c ofthe cast-iron ring and partly through the ring-gear, as plainly shown in Fig. 7, and at their threaded ends the bolts pass through the edge-liange c of the cast-iron ring. By screwing up the nuts upon the bolts-it will be seen that the heads which project sidewise from the bolts in only one direction are drawn rmly against the ring-gear, and it is held to its seat upon the cast-iron ring and against l the peripheral edge-ange thereof. In this way the parts may be readily connected and separated, are rendered very durable, and repairs are greatly facilitated,.as will be obvious.

Flanged ring wheels or tires E, `preferably of steel, two for supporting each cylinder,

' are each formed and secured in place in the following way: Bands E E are secured about the cylinder on opposite sides of its center, or near each end, and a cast-iron ring, F, is bolted about each band. The bolts f and their nuts, which secure the cast-iron rings about the cylinder, also secure or assist in securing the,

bands E' in place. The rings F are formed at intervals with cross-ribs n, with intermediate recesses in their peripheries, and upon one;

` those above described in connection with the the ring-wheels prevent downward endwisev i movement of the cylinders, as will readily be lring-gear. These bolts are at the cross-ribs n.

v In this way separation of the parts is rendered easy to facilitate repairs, and great strength attained. Supportingrollers H, preferablyy of chilled iron, four for each cylinder, and arranged in pairs on opposite sides of each ofthe ring-wheels, are suitably mounted upon appropriate supports secu-red to the vessel, and projecting from the sides thereof, such as those, K K, represented in Fig. 12. The iianges of understood by inspection of Figs. 1 and 12. Rotation is imparted to the cylinders by meansd of bevel-pinions I I meshing with the beforedescribed bevel ring-gears B B. 'The bevelpinions are secured upon inclined shafts actuated by suitable connection with any appropriate motor.

The water for washing the material is conducted to the upper or outer ends of the in* clined cylinders by means of. pipes supplied from any suitable source; or, if preferred, and as in this instance shown, perforated pipes N may be` employed extending the whole length of the cylinders. The material to be washed is supplied to the cylindersat their lower ends by means of a forked cond-uctor or chute, J, as shown iu Fig. 1l, and when long perforated pipes are employed their lower ends may be supported by being attached to the forks of the conveyer, as shown. The pipes are suitably supported at the outer ends of the cylinders by braces O, connected with the supy porting-arms K K.

For the purpose of separating from the washed material and carrying off such refuse y not to interfere with the proper loading upon lighters of the washed material as discharged from the outer ends of the cylinders. At their IOO lower ends the water and refuse substances run from the cylinders into a central well, M, in the hull.

For the purpose of enabling either one or both of the cylinders to be operated at the same time, suitable cut-offs-such as sliding gatesare provided in the forks of the conductor J.

From the above description it will be seen that a most thorough cleansing of the material is accomplished, as provision is made for the escape of refuse substances, both as rst delivered to the lower end of the cylinder and at the upper end of the cylinder, as well as by being washed downward by the flow of water.

` It is obvious that the apparatus above described may be located upon any suitable frame-work or structure instead of being arranged upon the vessel-hull, and that only one cylinder may be used.

I am aware that it is not new to provide inclined rotating cylinders or equivalent structures withinternal spiral ribs or rib-sections, in addition to means for supplying the cylinders with water, so that the finer and refusev IIO particles may be discharged at the lower ends of the cylinders and the material to be saved conveyed to and discharged from the upper ends; and Ido not broadly claim such apparatus. Neither do I unqualiedly claimacylinder having perforated sections, as such is old.

I claim as of my own. invention- 1. The inclined rotating cylinder having the inwardly-flaring perforated loWer section, the outwardly-flaring perforated upper section, and spirally-arranged rib-sections, substantially as and for the purpose hereinbefore set forth.

2. The combination of the inclined rotating washingcylinder imperforate for the greater portion of its length, and having the rib-sections, the perforated outwardly-flaring outer section of the cylinder, and the chute by which refuse material passing through the perforations of said outer section is conveyed away beneath the imperforate portion of the cylinder and toward its lower end, substantially as and for the purpose hereinbefore setforth.

3. The combination of the cylinder, the ring C', having the peripheral edge-Hange c', the

ring-gear constructed independently of said ring, and the securing bolts and nuts by which the ring and ring-gear are detachably connected with each other, and these parts secured to the cylinder, substantially as and for the purpose hereinbefore set forth.

4. The combination of the cylinder, the ring F,'the flanged ring-Wheel, and the bolts and nuts by which it is secured in place, substantially as and for the purpose hereinbefore set forth.

5. The combination of the cylinder, the ring C', secured thereto, and having inner and outer flanges, b c, and the peripheral flange c', the

as and for the purpose hereinbefore set forth.

7. The combination of the cylinder, thering F, secured thereto, and having the shouldered flange G, and shorter flange g upon its opposite edges, the ilanged ring-Wheel, and the securing bolts and nuts by which the ring-Wheel is secured in place, substantially as and for the purpose hereinbefore set forth.

5 S. The combination of the cylinder, the band E, the ring F, bolted to the cylinder Withthe band, and formed With the cross-ribs n, the

shouldered flange G, and the shorter flange g,

the flanged ring-Wheel, and the bolts and nuts by which the ring-Wheel is secured in place, substantially as and for the purpose hereinbefore set forth.

In testimony whereof I have hereunto subscribed my name this 5th day of January, A. D. 1884.
